I use carnetts 78 all the time. They are always very helpful and couteous, I once forgot to have them repair a slow leaking tire after I already left having my car washed and oil changed. I turned around in the parking lot and told the guy at the service bay. Well, he plugged it AND DID NOT CHARGE ME!! He just said don't worry about it, your a regular. I wish I could remember his name. He is a thin, medium height quiet type guy with a mustache in his late 40's or early 50's. Next time I go up there, he gets a tip from me (I had no cash at the time and paid with a debit card).

The first time I went to this location at 4175 Stn Mtn Hwy in Lilburn Ga the whole inside of my car was smeared with something black all over my seats and the interior. They denied doing anything to my car. I only came there to get my car washed. I had cleaned my interior the day prior to going there. So I took my car to the location on Carnett's 1382 Pleasant Hill Rd Lawrenceville, GA 30044 and told them what happend at their Stone Mountain location. They apoligized and cleaned the black stuff off my seats, and interior. I have not been back to support this business since. I don't trust this company. I clean my own car now.
